>True.  And I just came across a questionable-date format in an example
under the 375 $s on the MARC21 site.


>But I don't want to rely on a single example as support for applying
EDTF date formats 

That's not an example of an EDTF date format. It's an example of the way
RDA indicates that uncertain dates should be recorded (e.g. in
ISO 8601 and edtf dates are only recorded in 046. Part of the problem is
that there would be no way to indicate what date standard you are using
in 37X.
